Effects of low fructose diet on glycemic control,lipid profile and systemic inflammation in patients with type 2 diabetes: A single-blind randomized controlled trial

Background and aimType 2 diabetes is one of the global epidemic disorders, which causes many side effects on the body. Fructose is a lipogenic monosaccharide. Recent studies have reported the adverse effects of this carbohydrate on diabetes. This study aimed to evaluate the clinical efficacy of a low-fructose diet on the metabolic alterations in patients with type 2 diabetes.MethodsThis study was a randomized, single-blind clinical trial on 50 patients with type 2 diabetes. Participants randomly allocated to two groups, to receive either diabetic-diet or diabetic-diet with low-fructose for 8-weeks. Anthropometric measurements, systolic blood pressure (SBP), Diastolic blood pressure (DBP) and metabolic factors were assessed at baseline and the end of the trial.ResultsAt the end of trial, reduction in body weight, waist circumference, and blood pressure were not significant except for DBP (P = 0.013). Statistical analysis showed that low-fructose diet compared to control group significantly declined fasting blood glucose (FBG), Hemoglobin A1c (HbA1c), Triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C) and high-sensitivity C-reactive protein (hs-CRP) (P = 0.015, P = 0.001, P=<0.0001, P= <0.0001 and P= <0.0001 respectively).ConclusionOur results showed that eight weeks of low-fructose diet results in a significant improvement in FBG, HbA1c, TG, HDL-C and hs-CRP in patients with type 2 diabetes.
